触媒剂

IT IS MONOCLINIC CRYSTAL. IT IS EASILY SOLUBLE IN WATER, LIQUID AMMONIA AND AICOHOL,DOLIPUESCC IN THE AIR, BURN AND OXPLODE WHEN MIXING WITH ORGANICS. IT IS USED AS DEHYDRANT OF MAKING NLTRATE, CINERATION AND CHEMICAL EXPERIMENTATION ETC.

无色透明单斜晶体，易溶于水、甲醇、乙醇，在空气中极易潮解，与有机物混合会发热，有着火及爆炸危险，工业上用作浓硝酸的脱水剂，制造炸药，用作触媒及其他镁盐和硝酸盐的原料，小麦灰化剂，在实验室用作化学剂。

Sufficient tinderstanding and command of different roles such as question-master, prolocutor, director and activator and so on is conducive to activating classroom atmosphere, improving teaching quality and cultivating different abilities in students.

隶例教学中教师对主持人、发言人、导演者、触媒剂等角色丛的充分理解和把握，有助于活跃课堂气氛、提高教学质量、培养学生多方面能力。

Passivation process also has some drawbacks, including hard buck coke catalyst bed treatment、polythionic acid stress corrosion cracking prevent for sensitively materials, meanwhile passivation process must be coordination between skillful local workers with knowledgeable company.

钝化法也有一些潜在的缺点必须注意，同时也是需要厂商负责保证，主要包括大块结焦废触媒的处理、钝化剂化学成分是否会对设备材质造成潜在伤害的确认及设备因敏化而产生聚硫酸应力腐蚀的预防等。

The best catalytic activity and selectivity could be found in the prepared catalyst system with the optimum combination of the ionic liquid, nano-Pd, and support. The stabilizer is also used to prevent the aggregation of nano-Pd particles. One of the advantages of this approach is that the prereduction of catalyst is not required.

其中离子液体、奈米钯金属及担体皆有其功能，三者之组合才能达到良好之效果，同时，在合成奈米钯过程中，必须使用稳定剂以避免奈米钯金属之聚集此触媒系统之另一优点为不需先加氢还原处理，耐水性强且可重覆使用，是一种颇具潜力之选择性氢化触媒。

The equipments to be imported within the projects total investment in terms of value and for internal use and the unappraised equipment provided by foreign investors in their processing terms are exempted from tariffs and VAT related to import .

关税。在投资总额内进口或利用国际贷款进口的自用设备、加工贸易外商提供的不作价设备，免征关税和进口环节增值税；为生产出口产品而进口的原材料等予以保税；在生产出口产品过程中的消耗、触媒剂、催化剂、磨料、染料等免收进口关税和增值税，出口的自产产品免征出口关税。

As when used as specialty lamps for diazo-printing reprography, lithography, insect traps,photochemical and curing processes containing phosphors such as SMS (Sr, Ba 2MgSi207:Pb

磷化学和含磷食物加工过程的专业灯时，放电灯中的萤光粉触媒剂的铅铅含量

Lead as activator in the fluorescent powder (1 % lead by weight or less) of discharge lamps when used as sun tanning lamps containing phosphors such as BSP (BaSi2O5 b) as well as when used as speciality lamps for diazo-printing reprography, lithography, insect traps, photochemical and curing processes containing phosphors such as SMS (Sr,Ba2MgSi2O7 b.

放电灯中的萤光粉中作为触媒剂的铅含量在其重量的1%以下，当放电灯用作含磷仿日晒灯，比如含有BSP(BaSi2O5 b)，以及用于重氮复印、平版印虫器、光化学和食物加工过程的含磷特种灯时，比如SMS(Sr，Ba2MgSi2O7：Pb 。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
